"There’s definitely a problem in our community and across the country where things like this are happening to these pets who can’t really fend for themselves," she said.

That's why it's critical that witnesses document and report instances of abuse. Nelson said witnesses should not put themselves in harm's way, but they should try to get proof of the abuse.

"If there’s any way you’re able to get photos, video, a license plate, anything like that will help authorities so much in determining their next steps and where to begin looking for this act of cruelty," Nelson said.
